v lMPF-IOVEMENT IN CLCVER-SEPARATORS.

To all whom it may concern:

Be it known that I, OHARLEs L. ALLEN, ot' Flat Rock, in the county 4of Wayne and State of Michigan, have invented a new and 'useful Improvement in Clover-Separators;

and I do declare that the following is a true Vand accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specication, in which- Figure lis a perspective view of the shoe ofa clover hulling and separating machine with my improvement attached. Fig. 2 is a cross-section on the line :c in Fig. l. Fig. 3 is a plan of the outer end of the shoe 5 and Fig. 4 is a longitudinal vertical section taken on the line y y in Figs. 1 and 2.

Like letters refer to likeparts in each iigure.

This invention relates to a separating attachment to the shoe ofa clover hulling, thrashing, and separating machine; and has for its object to eliminate all the seed from the impurities,iwhich will be discharged in their first passage through the machine, instead of beingy returned through the machine several times to be reground and cut up, as heretofore. The invention consists in a double inclined spout vprovided with separating-screens attached to the outer end of the shoe, and so arranged as to electually eliminate the seed from the impurities not extracted by the principal seed-screen of the shoe.` l

In the drawing', A represents the shoe of a clover hulling and separating machine, provided with the coarse screen B and fine screen C and seed-spout D, as heretofore, and to the invention of which I make no claim. This shoe is hung in the casing of a clover-machine, and is vibrated in the usual manne-r, the blast from the fan entering the shoe at the left of Figs. 1 and 4. Across the discharge end of the shoe at the bottom, and

l.partition is carried up to the plane of the coarse screen B, which terminates at its edge, as seen in Figs. 1 and 4, the end of the said screen being broken away in Fig. 3. The et'- fect of' this arrangement is thatthe chaff and heads fall over the screen into the outer di- 'vision of the trough or spout E, and are discharged at the side of the machine, while the clover seed and stubs fall through the coarse upper screen onto the lower ne screen, through which the greater proportion of the seed sit'ts into the bottom of the shoe, whence it is discharged by thc spout D, while the remainder passes with the stubs over the end of the ne screen onto a ine'r screen, F, inclined to the left in the nearest division of the spout E, through which the seed sifts to the bottom of said spout-division; but, in-

stead of passing out at the right-hand end spout is inclined to the left, and in it is a screen, H, inclined to the right. The refuse matter and some little remaining seed which is discharged from the screen F above fall onto this screen H, which discharges the impurities passing over its surface at the right, while the'seed sifts through and is discharged at the left.

In clover hulling and thrashing machines as heretofore constructed the heads, stubs, and everything, except the chaff blown away, passing over the first pair of screens, are taken by a short elevator at the side of the machine and carried back to the cylinder to be ground up so that it will pass through the iirst screen, and thus eliminate the seed in its second screening. A large proportion of the matter goes through this process the second'time, and often the third. l In this ma chine the available seed is separated at the first passage through the shoe and screen spouts, saving the expense of the elevatorabout ten dollars-and the time and power of or d, spout G, nud its screen H, substantial y running the elevator and regrindng the maas shown and set forth, and for the purpose terial. specified.

What I claim as my invention, and desire CEAS. L. ALLEN. to secure by Letters Patent, is-

The construction and arrangement, with Witnesses: relation to the shoe A, screens B C, spout E, JOSEPH A. PIERsoN, and screen I", of the partitions a b, conduct CHARLES H. BALL.
